Abstract (en)

[origin: EP1512417A1] An object of the present invention is to provide a particulate water-absorbent resin composition which is so excellent that: the absorption ability in an initial short time is secured in some degree, and further, the absorption capacity lastingly increases over a long period, and also the liquid permeability and the liquid diffusibility can be secured. As a means of achieving this object, a particulate water-absorbent resin composition according to the present invention is a particulate water-absorbent resin composition comprising a carboxyl-group-containing water-absorbent resin in an amount of not smaller than 80 mass %, with the composition being characterized by being: not less than 20 g/g in specific-particle-diameter absorption capacity under load (0.29 psi (2.00 kPa), 1 hour); and not less than 3 g/g in specific-particle-diameter absorption index increment in 20 hours. <IMAGE>
